Our oil filtration plants are used to remove impurities from transformer and switchgear oil such as moisture, dirt, air and other gases. This is a `low temperature and high vacuum` principle based equipment as per the International Standards 6034 (1989) and its latest revision. We manufacture plants of variable capacities of 1200 to 25, 000 lph which can be customized to special capacities if required by the clients. This plant takes the impure oil into the system through the inlet ball valve and then pumps it through by a positive displacement pump. A filter prior to this removes solid particles up to 1mm size and magnetic particles. After heating the oil up to 60c it passes through the cartridge filters, where particles up to 5 microns are filtered. A specially designed vacuum chamber removes moisture, air and all the gases with the help of vacuum. The oil falls by way of gravity over the media inside forming a thin film of oil, exposing a larger surface area. The dissolved moisture and gases are evacuated and the oil is ready.

During its operation of generating, transmitting and distributing power transformers give out heat which is absorbed by insulating oils. This oil has a tendency to absorb moisture from windings which leads to gradual deterioration of dielectric strength. Our filtration systems provide economical and efficient methods of purifying this lubricant. The unit consists of:

Filter Unit,

Indirect system of Oil Heating,

Vacuum Dehydration / degasification Unit

Condenser and condensate receiver

Feed and delivery pump

Piping & Valves

Control Panel

Components of Plant:

The filter unit is a coarse strainer with a wire mesh filter element for retaining solid particles and a powerful magnet for retaining magnetic particles. It has round filter paper discs held under spring compression. Specially designed heaters with low watt density heat the auxiliary heating oil, which in turn heats the transformer oil maintaining a temperature of 70-80 C. The cylindrical external pressure vessel is fitted with various shallow drip trays and a specially designed spray pipe to increase surface area. The vapor from dehydration chamber is condensed in a condensate receiver of welded M. S. construction. There are feed and delivery pump of rotary gear type coupled directly with motors. Water Separator Collect the water produced. A centralized control panel has indicators for all electrical devices.
